Struct SeqSet 

pub struct SeqSet<T>
where
    T: Eq + Hash + Clone,
{ /* private fields */ }

A Set collection that maintains a deterministic insertion order.

Implementations

impl<T> SeqSet<T>

where T: Eq + Hash + Clone,

pub fn new() -> Self

pub fn insert(&mut self, value: T) -> bool

Inserts a value into the set.

Returns true if the value was not present in the set. Returns false if the value was already present.

pub fn contains(&self, value: &T) -> bool

Checks if the set contains a value.

pub fn remove(&mut self, value: &T) -> bool

Removes a value from the set.

Returns true if the value was present and removed. Returns false if the value was not present.

pub fn len(&self) -> usize

Returns the number of elements in the set.

pub fn is_empty(&self) -> bool

Returns true if the set contains no elements.

pub fn iter(&self) -> SeqSetIter<'_, T>

Returns an iterator over the elements in insertion order.

pub fn iter_mut(&mut self) -> SeqSetIterMut<'_, T>

Returns a mutable iterator over the elements in insertion order.

pub fn clear(&mut self)

Clears all elements from the set.

pub fn to_vec(&self) -> Vec<T>
